You can rule out Kanye West and Eminem, Simon hates rap music. I'd imagine Lady GaGa is a dead certainty with "Born This Way" out in November, I'd also expect a Michael Jackson week to promote his first posthumous album too. Katy Perry will no doubt have had Firework over and done with by then so maybe Last Friday Night (T.G.I.F.) as her next single?!
